Precautions for Crusher Operation

Prevent machine tipping over and damage to the front
attachment. Observe the following precautions for crusher
operation.
d
WARNING: Machine stability is reduced as crusher is
much heavier than the bucket. When operating with
a crusher, the machine is more apt to tip over. Falling
or flying objects may hit the cab or other part of the
machine. Observe the following precautions and take
any other precautions necessary to prevent accidents
and machine damage from occurring.
 Do not allow the machine's weight to be supported by
the crusher or bucket cylinder with the bucket cylinder
fully extended or retracted. Failure to do so may result
in damage to the front attachment. In particular, avoid
doing so with the bucket cylinder fully extended, as the
front attachment will be easily damaged.
Take care to prevent this from happening when
dismantling foundation structures using the crusher.
 Using the front attachment, do not raise the base
machine off the ground with the arm cylinder fully
extended. Failure to do so may result in damage to the
arm cylinder.
 When a heavyweight attachment such as a crusher is
installed, avoid quickly starting or stopping the front
attachment. Failure to do so may result in damage to the
front attachment.
 Do not attempt to perform crushing on either side of the
machine. Always perform crushing operations to the fore
or rear, parallel with the tracks. Otherwise, tipping over
may occur.
